Methods, systems, and devices for monitoring anisocoria and asymmetry of pupillary reaction to stimulus

Abstract

A computer program is disclosed for performing the following method: recording images of a response of a left pupil to a stimulus thereby resulting in a first set of sequential images; recording images of a response of a right pupil to the same stimulus at the same time as the first images were recorded, thereby resulting in a second set of sequential images; displaying on a display simultaneously the first set of images and the second set of image, wherein the two sets of images are synchronized, and wherein a center of the left pupil of each image from the first set of sequential images is aligned with a center of the right pupil from the second set of sequential images on the display.

We claim: 
     
         1 . A method of assessing a health condition of a mammalian subject comprising:
 using a monocular handheld pupilometer to record images of a response of a left pupil of the subject to a first level of light stimulus;   using said monocular handheld pupilometer to record images of a response of a right pupil of the subject to said same first level of light stimulus;   using the pupilometer to provide an output comparing the response of the left eye to the response of the right eye; and   determining whether there is asymmetry in pupillary response between the left eye and the right eye.   
     
     
         2 . The method of  claim 1 , wherein the mammalian subject is a human. 
     
     
         3 . The method of  claim 2 , wherein the output is a graphical representation of the pupillary response of the left and right pupils superimposed together on a single graph.
